signalk-shrpi-monitor

Signal K Node Server Plugin for Sailor Hat monitoring (based on signalk-rpi-monitor)

Reports:

• Input Voltage
• SuperCaps Voltage
• Input Amperage
• MCU temperature (Kelvin)
• System Status

In order for the plugin to work, the Sailor Hat software must be installed and configured on the host device.

Additionally the unix socket for accessing data must be available to the SignalK service. This is configurable through the plugin options. If you are running SignalK in a docker container, make sure to pass the socket into the container.

If you are using docker-compose, you can reference the socket like this:

  signalk:
    image: signalk/signalk-server:latest
    ...
    volumes:
      - /var/run/shrpid.sock:/var/run/shrpid.sock
      ...

You will also need to grant permissions to the socket to be used by non-root user, since the default permissions for the socket are root. To allow anyone to read/write to the socket:

sudo chmod a+rw /var/run/shrpid.sock
